Mapping method, node, communication device and storage medium

Abstract

The invention discloses a mapping method. The method comprises the following steps: a distributed unit IAB donor DU in an access and return integrated host node receives a signaling message and firstindication information sent by a centralized unit IAB donor CU in a network element of the access and return integrated host node, wherein the first indication information is used for indicating the signaling type of the signaling message;the IABdonor DU maps the signaling message to a transmission channel corresponding to the signaling message according to the signaling type of the signaling message and sends the signaling message to an access backhaul integrated node IAB node, and the signaling type comprises an F1AP message related to the access terminal or an F1AP message unrelated to theaccess terminal. According to the method, the node maps the signaling message to the corresponding transmission channel and sends the signaling message to the next node after receiving the signaling message, so that the priorities of the signaling messages can be distinguished, and the signaling transmission quality is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a mapping method, a node, a communication device and a storage medium. Background technique [0002] Integrated access and backhaul (IAB) is an important part of the fifth-generation mobile communication technology (5G). Integrated access and backhaul donor (IAB donor) Connect to the 5G core network 5GC through the NG interface, and connect to the integrated access and backhaul node (IAB node) through the Un interface to the IAB donor, thereby forming a link for signal transmission, and the user equipment (user equipment) , UE) only needs to access the IAB node to access the 5G network. It is worth explaining that the interface between IAB donor and IAB node can be called Un interface or other interfaces, which is not limited. This patent uses the name of the Un interface as an example for illustration. [0003] Based on the above architecture, the signaling inte...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, multiple types of signaling transmission are supported on the backhaul link, but the bearer mapping method of these signaling on the backhaul link has not been discussed yet

If the type of signaling is not distinguished on the backhaul link, low-priority signaling may be processed before high-priority signaling, resulting in link errors and affecting network performance.
